Fair point. I actually wasn't aware that there was a home port of Ali Baba; it seemed sufficiently obscure enough that the game was something of an odd candidate for porting from the arcade. Then again, there's Espial, and that made it to a number of home platforms.

True. Another possibility: Ali Baba was developed outside of Sega, licensed or bought in, and had their copyright slapped on it without complete code review (or with, and they decided to turn a blind eye to it). Then again, the hardware (judging from the MAME driver) looks to pretty much be vanilla Pac-Man, so it's not clear to me how someone at Sega could have missed that similarity two years after Pac-Man had had time to flood the market.
Either way, it's an interesting one. I really hope that more info as to its origins crop up some day.
